I recently purchased the E07K for my BeyerDynamic DT770 80 Ohms as I have been previously driving them from the front I/O port on my PC and my iPod. After using the E07K I instantly noticed that the audio was "cleaner" and the bass cleared itself up very well.

I'm no audio engineer so I can't give a super in depth review on them (Although many head-fiers already have) but I have found it to be an extremely good investment for my particular headphones.

Hi.

Wich amplifiers didático you consider Before getting this one?

I am thinking about buying an ipod and an amp or amp+dac for it.

The only others I really considered were the E10 and the E17. But spec wise the E07K is almost identical to the E17 and far cheaper.
